"Travelling is difficult right now, because we are in quarantine."
Translation:Matkailu on nyt vaikeaa, koska olemme karanteenissa.
It's also a stupid sentence in either language, because travelling is not "difficult" when one is in quarantine, it should be non-existant.
There has been a lot of confusion about the different terms, such as quarantine, here in Finland during the pandemic, and I think this sentence is a symptom of that confusion. Quarantine is not at all the same as travel restrictions or a lockdown.
